Proxy checker
Paste up to 50 proxies, one per line. We open a real tunnel through each one from our server and tell you which are alive, which are dead and how fast they respond.

Frequently asked questions
Which formats are supported?
host:port, host:port:user:pass, user:pass@host:port, and the same with http:// or socks5:// in front.
How do you test a proxy?
For HTTP proxies we send a CONNECT request to example.com:443; for SOCKS5 we perform the full handshake (including login) and request a connection. A proxy is “alive” only if the tunnel is actually established.
Is my proxy list stored?
No. Proxies are tested in memory and never saved.
